Class SweptAreaSolid

SweptAreaSolid class

A SweptAreaSolid constructs a geometry by sweeping a profile along a directrix.

public class SweptAreaSolid : Entity, IMeshConvertible

Constructors

NameDescription
SweptAreaSolid()The default constructor.

Properties

NameDescription
Directrix { get; set; }The directrix that the swept area sweeping along with.
EndPoint { get; set; }The end point of the directrix.
Excluded { get; set; }Gets or sets whether to exclude this entity during exporting.(Inherited from Entity.)
virtual Name { get; set; }Gets or sets the name.(Inherited from A3DObject.)
ParentNode { get; set; }Gets or sets the first parent node, if set the first parent node, this entity will be detached from other parent nodes.(Inherited from Entity.)
ParentNodes { get; }Gets all parent nodes, an entity can be attached to multiple parent nodes for geometry instancing(Inherited from Entity.)
Properties { get; }Gets the collection of all properties.(Inherited from A3DObject.)
Scene { get; }Gets the scene that this object belongs to(Inherited from SceneObject.)
Shape { get; set; }The base profile to construct the geometry.
StartPoint { get; set; }The start point of the directrix.

Methods

NameDescription
FindProperty(string)Finds the property. It can be a dynamic property (Created by CreateDynamicProperty/SetProperty) or native property(Identified by its name)(Inherited from A3DObject.)
GetBoundingBox()Gets the bounding box of current entity in its object space coordinate system.(Inherited from Entity.)
virtual GetEntityRendererKey()Gets the key of the entity renderer registered in the renderer(Inherited from Entity.)
GetProperty(string)Get the value of specified property(Inherited from A3DObject.)
RemoveProperty(Property)Removes a dynamic property.(Inherited from A3DObject.)
RemoveProperty(string)Remove the specified property identified by name(Inherited from A3DObject.)
SetProperty(string, object)Sets the value of specified property(Inherited from A3DObject.)
ToMesh()Convert current object to mesh

Examples

The following code shows how to modeling an solid entity by sweeping a C-shape on a circle

var directrix = new Circle(20);
var shape = new CShape();

var swept = new SweptAreaSolid()
{
  Shape = shape,
  Directrix = directrix,
  StartPoint = EndPoint.FromDegree(0),
  EndPoint = EndPoint.FromDegree(130)
};

var scene = new Scene();
scene.RootNode.CreateChildNode(swept);
scene.Save("swept.obj");
